Application filed September 27, 1905. Serial No. 280,297.

To all whom it may concern:

.Be it known that I, JOHN R. SOHRADER, a l taken on line 3 3, Fig. '1.

[the same. Fig. 3 is a horizontal section citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

My invention relates to improvements in carbureters, and its primary object is to provide an automatic feed for saturating ab-' sorbent material, and by means of suction charge the air with hydrocarbon vaporsreleased from said absorbent material.

Other objects are to interpose an absorbent body between the air-inlet and gas-outlet of the casing and cause air by means of suction a plied to the said outlet to be drawn into tl ie-casing through the saturated body and out through the outlet in the form of gas for storage or consumption; to provide an absorbent body in the course of the air'passing through the carbureter and maintain said absorbent body in a saturated condition by capillary attraction or Otherwise, and also to' ing-chamber with suitable absorbent material'adapted to absorb the drip ings from thebottom; of the carbureting-c amber inthe event of the necessary heat being unobtain able to prevent sweating; to provide means for drawing a quantity of fresh air into the carbureting-chamber, so as to mingle with the, carbureted air, and to otherwise improve on carbureters now in use;

With these and other objects in view the invention consists in the construction, ar-

rangement, and combination of' parts to be hereinafter described, and particularly pointed out in the subjoined claims.

In the drawingaFigure 1 IS a central vertical section through a carbureter embodying my invention. Fig. 2 is a plan view of tal section'taken on line 4 4, Fig. 1. Fig. 5 is a transverse section'taken on line 5 5, Fig. 1. Fig. 6 is a detached perspective view of one ofthe removable-racks; to which the liquidabsorbing material is applied. Fig. 7 is a horizontal-section of the air inlet-showing an air-draft pipe applied thereto to aid the'suction apparatus in creating the desired aircurrent. I a

.Referring tothe drawings in detail, like letters of reference refer to like par s in the several figures.

The letter A designates the carbtuerercasing, which may be of any size or shape, but which is hereinshown as of rectangular formation and provided with oppositeend extensions a and a".v The extension a is tapered outward and'has secured thereto an air-inlet pipe B, which terminates in a funnel I), having its outer or'wide end provided with a' screen 12 to exclude paper or particles of foreign matter held in sus ension in the air,

or drawn to the inlet by t e suction applied to the carburetor. The extension a extends, by preference, the full width of the carbureter casing proper, as shown in Fig. 2, and consists of the end walls a, whichforma contimi- I ation of the sides of the casing, a horizontal upper wall. cand an inclined wall 0 extend- ,ing from the upper wall to the adjacent end wall of said casing. To the up er wall of said extension a gas-outlet pipe which leads to a compressor or to the combustion-chamber of an engine. When connected to an engine, the outward stroke of the piston thereof creates the necessary suction to cause the air to-be drawn into the inlet a through the carbureter and 'to the combustion-chamber of'the engine through outlet-pipe D. In the inlet-pipe is a butterfly-valve E, having its pivot-stem e projecting from the pipe and provided with a lever e, and in the outlet-pipe D a slide-valve F is "seciired, which is provided with an outstanding arm A connecting-rod G has opposite'ends secured to the armf of said slide-valve and to lever e" of'the butterfly-valve, respectively, its function being to cause both valves to act in unison. An inwardly-closing check-valwe Fig. 4 is a horizonis secured,

Surmountingthe carburetingcasing is a gasolene or other liquid-hydrocarbon rece tar Iprovidedwith'an o ening 6., which is covered by ahood or upw ardly-extending housing '5 perforated, as at 5 ,501 a purpose to be In the carbureting-chamber able fluid-absorbing body or bodies, Whichin a representative form are shown herein as ab.

.per ends thereof are held in the hood if, ex-' tending into the liquid-receptacle, thesides thereof being guided by lugs 7c, extending from the sides of the casing. In applying the absorbent cordor wicking one end of each cord is suitably secured to the end of the upthe course of the air, which is drawn through the saturated material and thoroughly carbureted.

' The casing is provided with a box-like bottom M, which is removable to ermit the in troductionof the racks L, the ower ends of the latter being. held between guides I, see cured-to the bottom. Said bottom consists of a bottom wall m and vertical walls m, that lie against the sides of the casing roper and have outstanding flanges 'm at t eir upper ends. Surrounding the lower end of the carbureting-casingis a casing. N, having a bottom n and side walls 11/, terminating in inwardly-directed flanges n, the side walls being separated from the carbureting-casing by intervening spaces a Flanges O are riveted or otherwise secured to the sides of the carbureting-casing, and passing through the same and the flanges m and'n respectively,

of the bottom and the casing N are bolts 0,

which secure the three parts together. Between ianges O and m a suitable packing O .is clam ed. I p 1 casing N is separated The ottom of the from the carbureting-casing by an interveni'. ing space 0,, which, withthe side-.spaces n form aheating-cham'ber 0 havingthe sides between the and-the gas-outlet I arrange a vs'nittrodnctlon of atmospheric air. iSaid chamthereof provided with apertures 0 for the inher is provided withpipes P, which may lead -.duce warm air to the chamber and prevent sweating-on the bottomm.

Thecarbureting-casing is divided into two chambers R and B, separated by a valve r and a screen S. Said valveis pivotally affixed suitable device, which is passed through the operative, the latter being limited in its up wardor opening movement by lugs r 6X".

The warm air in the heat-i "drawn throughthe absorbent material in} l at r and extends into the extension a of the a casing. Aihxed thereto is a 'cord 1 or other foregoing that the racks L; carrying the ab sorbent'matcrial, are located between valve 1- and screen S and that they extend from top to bottom of" the carbureting-casing. The latter is provided with a quantity of gasolene or other liquid hydrocarbon which is preferably maintained at a constant level by a float-controlled valve T, adapted to open and close the outlet of atube t, secured to the and having a valve t3: to regulate or close the supply. The lower, ends .of the racks L,

Provision may also be made to store a quantity of the gas by connecting to the carbureting-cham her a pipe a, which may be led to a compressor. The stored gas may be'used for startdrawn directly from the carburetor. A pipe ing the engine, after which the supply i V may be connected to .the inlet B'for the direct introduction of warm air without first leading the air through the heating-chamber.

In starting an engine or compressor, as the.

casemay be, the suction created causes the air to be drawn into the inlet a through the saturated absorbent body and'out-through. the outlet,for consumpt1on. Aricher, drier, and greater ield of gas. is obtained from a [Q given quantity of liqluid hydrocarbon by means of suction app ied to bring atmospheric air in contact with: the liquid than is possible .by a forced draftor by. the use'of. compressed air. Mgreover, the tank for compressed air is dispensed with, as is also.

When a large supply 1 of gas is needed, the valve 1* is elevated to the I position shown indottedlines', Fig.1,wh1ch' 2'0 permits a-portion'of the air to be drawn mt'o por- 1 the lower chamber R through'the lower tion of the absorbent material", thence 11 through the screen S, and finally out through the gas-outltl), with the gas generated in 2 5 the upper chamber.

--To prevent the liquid the bottom of the casing from being vaporized directly without first being absorbed by the'absorbent body, a

baffle-plate V is located beneath the screen'SQ 39 As shown in Fig. 7, the exhaust W 'of a fan,

compressor, or other current-inducing means may be securedjdo the air-inlet of the carbui reter to create a forced current of air. This may be desirable where it isnecessaryto increase the yield of gas or when the suction ap-- plied is too weak, in which latter case the forced current servesas an aid to the suction,

This invention is' susceptible to many changes in form, "construction, arrangement,

4 and combination of parts without departing from the spirit thereof or sacrificing any of its. advantages.
